Film Capacitors

Film capacitors or film dielectric capacitors, sometimes called Polyethylene Naphthalate (PEN) film capacitors, are passive components primarily used for AC signal filtering; they are analog parts used in AC power line filtering, and AC power amplifier circuitry. They consist of two metal plates separated by a film of PEN dielectric material, with a set of terminals connecting them to external circuitry.

BFC241704703 Application Field and Working Principle

The BFC241704703 is a Polyethylene Naphthalate (PEN) film capacitor used for AC signal filtering. It is rated at 400V, with a tolerance of 10%. It has a capacitance range of 2.0 to 2.2 microfarads and is suitable for frequencies up to 100kHz. The operating temperature range is -40℃ to 125℃.

The BFC241704703 works by storing electric charge on two metal plates separated by a dielectric material, usually PEN film. The dielectric material is chosen for its ability to withstand a certain voltage and temperature before it breaks down. When an AC voltage is applied, an electric field is generated between the two plates, causing the capacitor to draw a current which is determined by the capacitance of the device.

The BFC241704703 has an aluminum oxide film coating on the two metal plates to provide insulation and help reduce the effects of electrical noise. The body of the capacitor is made from thermally stable PEN film, which keeps the capacitance at a consistent level even at higher temperatures. It is also highly resistant to moisture, which makes it suitable for use in humid environments.

The BFC241704703 is used primarily in AC power line filtering applications, such as in power supplies, electronic ballasts, AC motor controls, and other electrical equipment. It can also be used in AC power amplifier circuits, where it helps to reduce the effects of electrical noise and limit the current flowing in the circuit. Additionally, it can be used in AC signal filtering applications, such as in home theater systems and radio and television receivers.

The BFC241704703 is a reliable and cost-effective solution for AC signal filtering. Its wide range of operating temperatures, noise dampening ability, and resistance to moisture make it a suitable choice for both industrial and consumer electronics applications.
